FRANCIS S. WALDO, OF ALAMEDA, CALIFORNIA.

SODA-WATER APPARATUS.

` SPBGIFICATIN forming part of Letters Patent No. 264,586, dated September 19, 1882.

Application filed July 1, 1882. (No modclf) To all whom it may concern Beit known that I, FRANCIS S. WALDo, a

citizen ot' the United States, residing in Ala- K ot' supplying acid from the'head or chamber to the generator; and it includes a novel construction and application-ot'Y suchchamber, whereby theysupply ot' acid to the generator is under complete control, and all danger of excessive flow of acid and the explosions incident thereto are'entirely obviated.

The following description fully explains the nature of my said invention and the manner in which I proceed to construct, apply, operate, and use it. The accompanying drawing, therein ret'erl ed to, shows a perspective view ot' a genera-tor, gas-coolers, and fountains to which my improvements are applied.

My improvements consist in making the acid-head a detached separate chamber from the generator, and, by an arrangement of pipes provided with suitable valves, making connection between the two in such manner that the pressure in the two chambers can be equalized, and the iiow ot' acid to the generator consequently arrested, and by the pressure in one and over the other increasing a iiow of acid is produced as often as required.

The construction is as follows: The acidhead A is a separate chamber, connected with the generator a by the pipe B, and also having the space above the end connected with the. top of the generator by an equalizng-tube, O, provided with a valve, D. The pipe B leads down into the acid, and when communication between the gasspace ot' head A and the generator is shut ott'it operates, like a siphon, to draw over a certain quantity of acid as often as gas is taken from the generator.

The pipe O is used to restore equilibrium of pressure between theV two chambers A a and stop the flow ot' acid. For this purpose it has a valve, D, which, when opened, gives equal pressure ot' gas in both chambers and stops the action of the siphon, and, when closed, sets it in operation.

In starting the apparatus it is necessary to have sufficient pressure of gas in the acid-head to produce atlow ot' acid through the pipe A. To accomplish this I make connection oi the lacid-head or the pipe O with the cooler g by means of a pipe, E, having a valve, f. This serves to lead over from the coolersutcient gas to give the'requir'ed pressure above the acid. This is a simple and effective way ot' obtaining pressure in the acid-head to set the apparatus in operation. This could also be produced by providing a small hand-pump, to be connected to the acid-head when required for use; but the construction here described is simple and sutticient.

The advantage of my improvement over the usual construction and application ot' acidchambers having direct communication between the acid-chamber and generator controlled by a plug or other valve consists in its being altogether separate from the generator. Havinggno valves to corrode and get out ot order, it is impossible for any explosions from excess of acid through leaky valves to take place in the generator.

Having tnus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. The acid head or chamber A, having "the` y acid-pipe B, the equalizing-pipe O, and a means for giving required pressure upon the acid in starting the apparatus, substantially as described.

2.' In a soda-water apparatus, the combination, with the generator, of the detached acidchamber A, the Siphon-pipe B, the equalizingpipe O, with its valve l), and a means for producing pressure in the acid-chamber in starting the apparatus, substantially as described.

3. The combination, with the acid-chamber A, of the pipe E, having valve f, connecting the acid-chamber with the cooler or other source ot' gaseous pressure in the apparatus.

Witness my hand and seal.
